The surface treatment of solar mounts can be done in different ways to enhance their weather resistance, corrosion resistance and aesthetics. The following are some common surface treatments for PV bracket:

Hot-dip galvanizing: Galvanising is a common surface treatment that is widely used for PV mounts. It involves dipping the bracket components into a hot-dip galvanising bath to attach a zinc layer to the surface. This zinc layer provides good corrosion resistance and prevents the bracket from rusting and corroding in harsh environments.

Powder coating: Spray coating is a common surface treatment used to add protection and aesthetics by applying a layer of powder coating to the surface of the bracket. The powder coating can be selected in different colours and textures as required to meet design and aesthetic requirements. The spray coating also provides a degree of corrosion resistance, enabling solar bracket to be used in outdoor environments for long periods of time.

Anodizing: Anodising is a commonly used surface treatment for aluminium alloy supports. It increases the corrosion resistance and hardness of aluminium by forming an oxide layer on its surface. The oxide layer is also self-repairing, forming a new oxide layer to protect the aluminium when damaged.

Electroplating: Electroplating is a surface treatment that deposits a layer of metal on the surface of a support. Commonly used plating metals include chromium, nickel and zinc. The plating layer not only provides corrosion resistance and durability, but also adds texture and aesthetics to the appearance of the bracket.

The choice of finish usually depends on the material of the mount, design requirements, environmental conditions and personal preferences. When selecting a surface treatment, factors such as weather resistance, corrosion resistance, aesthetics and cost of the PV mount need to be considered. In addition, to ensure the quality and consistency of the surface treatment, it is recommended to choose a professional manufacturer or supplier who has extensive experience and the right equipment to perform the required surface treatment process.
